VALVE FOR SWIMMING BAGS.

Application filed August 30, 1926. Serial No..132,431.

The object of this invention is to provide a simple and effective valve through which to inflate woven fabric bags such as are used for buoyancy while bathing and swimming, and particularly for use in connection with swimming-bags such as are set forth in my application executed concurrently herewith.

in the accompanying sheet of drawings,

Figure 1 shows a valve which embodies this invention together with an extension portion of a woven fabric bag with which it is to be used.

Fig. 2 shows this portion of the bag before the valve is inserted.

Fig. 3 shows the mouthpiece used with the valve.

Fig. l shows the valve tube.

Fig. 5 shows the valve knotted.

A slender tapering bag extension 10 forming part of an inflatable woven fabric bag has a valve inserted into its end which consists of a mouthpiece 11 on which is slipped the larger end of a slender collapsible tapering valve tube 12 of woven fabric. The end of the bag extension is tied down over the larger end of the tapered valve tube onto the mouthpiece, the ends of the bindings l3, 13 which covers the seams of the bag being used for the purpose of binding to the mouthpiece. A metal ferrule let is closed over the binding for additional security. The valve fabric is of cotton which wets readily, is closely woven eighty to the inch or finer, and the valve tube is of such length and has its outlet end constricted so that the valve fabric when wet will be impervious to air and the valve will close from the pressure within the bag and be self sealing. The bag extension and the valve tube within are of such length and sufficiently slender so that they can be knotted if desired for additional security in closing the valve which may be desirable when used with a bag having two ply walls capable of holding air against a. higher pressure than the single ply fabric of the valve, if the valve is single ply. But 1 preferably make the walls of the valve each of two thicknesses of cloth, and it Will then hold the pressure without knotti'ng.

I claim:

1. In combination with an inflatable woven fabric bag, a valve consisting of a mouthpiece and a collapsible tapering tube of woven fabric within the bag, the mouthpiece being bound into the larger end of the tube, and the tube being of such length and with its outlet of such constriction that the tube will be self sealing by the pressure within the bag and exterior to the tube.

2. In combination with an inflatable woven fabric bag, a. valve consisting of a mouthpiece and a collapsible tapering tube of woven fabric within the bag, the mouthpiece being bound into the larger end of the tube, and the portion of the bag containing the tube and the tube being of such length and sufficiently slender so that they can be knotted.

3. In combination with an inflatable woven fabric bag, a valve consisting of a mouthpiece and a collapsible tapering tube of woven fabric within the bag, the mouthpiece being bound into the larger end of the 1 tube, and the portion of the bag containing the tube and the tube being of such length and sufficiently slender so that they can be knotted and the outlet of the tube being of such constriction that the tube will be self sealing by the pressure within the bag and exterior to the tube.

4. In combination with an inflatable woven fabric bag, a valve consisting of a mouthpiece and a collapsible tube within the bag, the walls of which each consist of two layers of fabric.
